  • Leontiev M.K., Ivanov A.V., Degtiarev S.A., Modeling of rotor dynamic sysems with spatial shafts location
    Spatial shafts Rod models of rotor systems and modal methods of their analysis are still in demand when solving of real-world problems of rotor dynamics of rotating machines. There are some algorithms and programs of such models analysis. Mainly the tasks at axisymmetric statement are solved. At the same time there are a lot of constructions where multiple shaft models of rotor systems with spatial axis position of their subsystems shafts, case elements and links between them - should be built. The article considers creation of motion equations of such systems that allow calculations of coupled bending-longitudinal-torsional vibrations of any spatial system including subsystems with parallel, skew, crossed axes. An example of such system calculation in the program system Dynamics R4 for calculation of dynamic characteristics of rotating machines is given.
